Hi, how do you achieve the sonic sounds heard at the intro of Climbing Up The Walls and Lucky?

*Insert snarky comment about the redundancy of “sonic sounds”.*

Intro of Climbing Up The Walls is predominantly a feedbacking spring reverb (that’s the high pitched noise) interspersed with radio noises/talking run through the Space echo. (At least, it sounds exactly like a feedbacking spring reverb, but it could be the EMT Plate reverb – I’ve never knowing heard one of those feedbacking before.)

Intro of Lucky is Ed strumming his Strat above the nut with a bunch of delay from some finely tuned Boss DD5’s.
